Thanks

Thanks to the following projects which we fully rely on to provide some of
our features:

• Python Extension
• debugpy

Also thanks to the various projects we provide integrations with which help
make this extension useful:

• Jupyter:
  Notebooks,
  JupyterHub,
  ipywidgets,

2020.12.1

Fixes

1. Fix support for IPyWidgets in Interactive Window.
   (#4203)

2012.12.0

Enhancements

1. Add support for IPyWidget in Native Notebooks. (#251)

Fixes

1. Information in the interactive window is python specific. (#340)
2. Allow user to cancel asking about logging level. (#348)
3. Watch for any addition of the python extension, and don't suggest a full reload when it is added. (#405)
4. Only offer to export to python script when the metadata specifies python as its language. (#407)
5. Hide webview based Notebook command Select Kernel when a Notebook is opened using the new VS Code Native Notebook editor. (#426)
6. Correctly pass the candidate interpreter when exporting. (#1363)
7. __file__ variable not set after restarting kernel in the interactive window. (#1373)
8. Fix the search path for Jupyter kernels on UNIX systems (thanks Giulio Girardi) (#3918)
9. Fix the directory for exporting from the interactive window and notebooks to match the directory where the original file was created. (#3991)
10. Fix variable fetching on remote machines that don't have our scripts files on them. (#4006)
11. Display survey prompt once per session. (#4077)
12. Guard against AttributeErrors in our DataViewer code. (#4082)
13. Ensure user cannot belong to Custom Editor experiment is already in Native Notebook experiment. (#4105)
14. Fix problems with code in UI getting out of sync with code being executed or saved to disk. (#1701)

Code Health

1. Added an onCreated event to the Interactive Window provider so external buttons can appear on creation. (#413)
2. Use notebookIdentity instead of the notebook when handling external buttons. It handles the case when the user doesn't autostart the kernel. (#414)

2020.11.2

• When removing our dynamically added editor associations always remove them if Native / Custom Editor is disabled, not just if we remember adding them. (#3988)
• Ensure survey prompt is not displayed multiple times.. (#4002)
• Migrate references to python.dataScience.* in when clauses of keybindings.json. (#1088)

2012.11.3
